| 摘要： | This study evaluates the rehabilitation method utilizing the injection of Uretek (polyurethane) into the pavement structures on continuously reinforced concrete pavement (CRCP), jointed concrete pavement (JCP), and bridge approach slabs. The polyurethane injection was used to fill voids and level the CRCP and bridge approach slabs. On JCP, it was used to reduce faulting, fill voids, and underseal. Testing results indicated that injecting polyurethane into the pavement structure is an effective method of leveling CRCP and bridge approach slabs. |
